Let's say you have a region in the buffer that has the text property
`shr-url' with the value "http://fsf.org/";, then:

(text-property-search-forward 'shr-url "http://fsf.org/"; t)

would place point at the end of that region, and `match-beginning' and
`match-end' would point to the start and end.

Sounds quite nice.

The `t' there is the predicate: `t' means "equal", `nil' means "not
equal", and then you can write your own predicates for other uses.

"Equals or includes" should be another popular predicate (think faces).
